执行正常

import requests
import re

class Get_mess():

    def __init__(self,url):
        self.url = url

    def get_words(self):
        req = requests.get(self.url).text
        pat = '<p class="de_con">(.*?)</p>'
        words = re.findall(pat,req)
        print(words)
        return words

    def get_tb_url(self):
        req = requests.get(self.url).text
        pat = '抢购：<a href="(.*?)" '
        tb_url = re.findall(pat,req)
        print(tb_url)
        return tb_url

    def get_img_url(self):
        req = requests.get(self.url).text
        pat = 'class="lazy MainImage" data-original="(.*?)"'
        img_url = re.findall(pat,req)
        print(img_url)
        return img_url

url = input('输入选单网商品url：')
message = Get_mess(url)
message.get_words()
message.get_img_url()
message.get_tb_url()

执行报错（下面执行已将图一中30行之后代码注释）

from Send_circle_of_friends import get_data
from Send_circle_of_friends import huajuan_login
from Send_circle_of_friends import get_url

url = get_url.get_url()
get_data.Get_mess(url)
tb_url = get_data.Get_mess.get_tb_url()
words = get_data.Get_mess.get_words()
img_url = get_data.Get_mess.get_img_url()

huajuan_login.login(tb_url,words,img_url)

报错：

说明：

不是很清楚为什么，在get_data文件中执行不会出问题，但是在main文件中导入get_data的函数进行调用会出现传参出错的问题，望指点，十分感谢！
